Description

Dual-line one-way unit output shaft processing line

Technical field

The invention relates to the field of shaft processing, and in particular to a double-line one-way device output shaft processing line.

Background technique

The output shaft processing of the one-way device requires four steps: boring and grooving of the end face - drilling of the center hole on the outer diameter end of the car - spline rolling - drilling of the tooth end face - boring and grooving. The performance of the lathe is basically the same. In this case, the four steps take different times. Therefore, when configuring the processing line, the lathe ratio of each section needs to be considered, otherwise there will be an empty machine waiting for materials or;

When processing a batch of output shaft blanks, when the single processing time of the previous process is short and the single processing time of this process is long, it will cause the accumulation of parts to be processed in this process, which will greatly affect the quality of the products.

Detailed ways

The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and examples:

As shown in Figure 1-8: Double-line one-way device output shaft processing line, including:

The first processing line includes a first conveyor belt, and also includes: three sets of boring and grooving equipment 21, three sets of center hole drilling equipment 22, and a set of spline rubbing equipment arranged at intervals next to the first conveyor belt. 23 and two sets of boring and grooving equipment 21, and the transportation path of the first processing line runs through the boring and grooving equipment 21, the center hole drilling equipment 22, the spline rubbing equipment 23 and the drilling and grooving equipment 24 (to be done later When describing in an inductive manner, for the sake of simplicity, the above four equipment will be collectively referred to as processing equipment, and the processing technology of the above four equipment corresponds to the processing technology mentioned in the background art);

The second processing line is arranged side by side with the first processing line and is separated by a certain distance. It includes a second conveyor belt and also includes: three sets of boring and grooving equipment 21 and two sets of center hole drilling equipment 22 arranged at intervals next to the second conveyor belt. And two sets of boring and grooving equipment 21; the second conveyor belt transfers the materials to the boring and grooving equipment 21 and center hole drilling equipment 22 of the second processing line in sequence, and then transfers them to the spline rubbing equipment of the first processing line. 23. Finally, it is transferred to the boring and grooving equipment 21 of the second processing line. The purpose of this setting is because, in the entire processing step of the one-way output shaft, the end face boring and grooving - the outer diameter end face drilling center Hole - Drilling of the end face of the tooth part - Boring and grooving are all drilling and cutting of the end face of the output shaft of the one-way unit. The processing time is long and the accuracy is relatively high, so the processing time is also relatively long, and Spline rubbing is to grind the outer surface of the one-way device, and the working depth is also shallow, so the processing time is short. Therefore, in actual production, the spline rubbing equipment 23 often appears to be empty and waiting for materials, which affects the processing efficiency. ; Then in order to improve the processing efficiency and make the spline rubbing equipment 23 operate at full load, the present invention proposes a double-line crossed production line layout structure, using the spline rubbing equipment 23 as the two production lines (the first processing line and the second processing line). The relay point allows the materials of the two production lines that have not undergone the spline rolling step to be uniformly transferred to the spline rolling equipment 23, and then dispersed again for processing, which is equivalent to using two lines to perform a long processing process at the same time. Short-term processing procedures can be shared, which saves the overall processing time of materials, reduces the waiting for materials before short-term processing procedures, and increases the average processing volume;

A loading mechanism 8 is provided at the starting end of the first conveyor belt or the second conveyor belt. In this embodiment, the loading mechanism 8 is provided at the starting end of the first conveyor belt for transporting the blanks to be processed; the loading mechanism 8 is provided at the starting end of the first conveyor belt. There is a workpiece correction mechanism downstream of the mechanism 8. Because the corresponding processing steps have different processing end faces of the one-way output shaft, it is necessary to determine the end face orientation of the material during transportation so that the surface to be processed faces the cutter head, so the workpiece is set Correction mechanism; downstream of the workpiece correction mechanism, the first conveyor belt is connected to the second conveyor belt, and a material distribution mechanism is provided at the connection point; as can be seen in Figure 1 of this embodiment, the material distribution mechanism is provided at the first The side wall of a conveyor belt includes a drive motor and a baffle plate. The baffle plate is arranged on the output shaft of the drive motor and can rotate inside the first conveyor belt to guide materials from the first conveyor belt to the second conveyor belt. , it should be noted that the logic of material distribution by the baffle plate is linked to the number of loading times of the feeding mechanism 8. The feeding mechanism 8 feeds the material for the first time, and the baffle plate closes the second conveyor belt, allowing the blanks to flow from the first conveyor belt. , when the feeding mechanism 8 feeds the material for the second time, the baffle plate rotates to close the first conveyor belt, allowing the blanks to flow in from the second conveyor belt. Such repeated switching can ensure that the feeding quantity of the first conveyor belt and the second conveyor belt remains relatively uniform, avoiding An empty aircraft situation occurs;

The boring and grooving equipment 21, center hole drilling equipment 22, spline rubbing equipment 23 and drilling and grooving equipment 24 are all provided with a first transfer mechanism 4 for transferring materials. The function of the first transfer mechanism 4 is to: The workpiece to be processed is transferred from the first conveyor belt or the second conveyor belt to the corresponding equipment for processing, and then the processed workpiece is placed on the first conveyor belt or the second conveyor belt and transported downstream. The main function of the first clamping mechanism is The function is to realize loading and unloading of corresponding equipment, which improves efficiency and reduces labor expenses compared to manual loading and unloading;

The first conveyor belt and the second conveyor belt are both provided with cutting mechanisms corresponding to the positions of the boring and grooving equipment 21, center hole drilling equipment 22, spline rubbing equipment 23 and drilling and grooving equipment 24. The function is to block the materials transported by the first conveyor belt and the second conveyor belt in front of the corresponding equipment to wait for processing; next to the cutting mechanism, there is a device for transferring the materials to the first transfer mechanism 4 and transferring the materials to the downstream of the cutting mechanism. The second transfer mechanism 5 has two functions in the present invention: ① transfer the material from the stopping mechanism to the established work station, and wait for the first transfer mechanism 4 to transfer it to the processing equipment; ② After the first transfer mechanism 4 puts the materials pre-transferred by the second transfer mechanism 5 into the processing equipment, the second transfer mechanism 5 picks up the remaining materials intercepted by the cutting mechanism, passes through the cutting mechanism, and is conveyed by the first conveyor belt and the first conveyor belt. Transport to the next cutting mechanism (i.e., the next processing equipment) to wait for processing to realize replenishment of downstream equipment; the second transfer mechanism 5 can effectively realize the coordinated replenishment of multiple equipment on the processing line; because the material It is transported on the first conveyor belt and the second conveyor belt in sequence, that is to say, all subsequent materials will be stopped at the first cutting mechanism; for multiple identical processing equipment in a certain section , since the material is intercepted at the front end, subsequent processing equipment will be waiting for materials. Therefore, the second transfer mechanism 5 is used to continue to transfer the material intercepted by the first cut-off mechanism to the downstream, which can ensure The same downstream processing equipment will not be short of materials;

The first conveyor belt and the second conveyor belt both include two parallel conveyor belts. The purpose of setting up the two parallel conveyor belts is that for a processing equipment, one conveyor belt feeds materials and the other conveyor belt discharges materials. , improves the efficiency of material transfer. If there is only one conveyor belt, after the materials are sent to the processing equipment for processing, the conveyor belt must stop and wait for materials, but with two conveyor belts, there will be no stopping of the belt to wait for materials;

In this embodiment, each conveyor belt is composed of two spaced conveyor lines. For the convenience of subsequent description, with reference to Figure 1, the two conveyor belts in the first conveyor belt are respectively marked as being far away from the first processing line processing equipment. The first conveyor belt and the second conveyor belt close to the first processing line processing equipment; and the first conveyor belt is composed of two conveyor lines A111 and conveyor line B112 set on the same horizontal line; similarly, the second conveyor belt includes Conveyor line C113 and conveyor line D114; the second conveyor belt includes: conveyor line E211, conveyor line F212, conveyor line G213 and conveyor line H214; wherein, the feeding mechanism 8 and the workpiece correction mechanism are both arranged on the conveyor line A111 (later described in When making an inductive description, for the sake of simplicity, the conveyor lines A-H will be collectively referred to as conveyor lines);

The two conveyor belts of the first conveyor belt or/and the second conveyor belt are both provided with extension sections 101 bent toward the rubbing spline mechanism, and the extension sections 101 are parallel to each other, because the rubbing spline mechanism needs to accept the second conveyor belt at the same time. The materials conveyed by the first conveyor belt and the second conveyor belt are processed, so the first transfer mechanism 4 next to the rubbing spline equipment 23 needs to transfer the materials to the first conveyor belt and the second conveyor belt (specifically: the conveyor line that accepts/transfers the first conveyor belt B112, conveyor line D114; material on the conveyor line F212 of the second conveyor belt, conveyor line H214), therefore, in order to reduce the displacement of the first transfer mechanism 4 next to the rubbing spline equipment 23 and speed up the two-way transfer time, an extension is set Section 101; in this embodiment, the extension section 101 is provided at the end of the conveying line F212 of the second conveyor belt and the starting end of the conveying line H214;

When the loading mechanism 8 puts a certain amount of material onto the conveyor line A111, it can adjust the transportation angle of the material to be consistent by reducing the width of the conveyor line A111, but it cannot guarantee the direction of the processing surface of the material. However, for lathe type processing equipment In other words, the corresponding processing procedure needs to determine the orientation of the material so that the processing surface faces the tool head; at this time, it is necessary to determine the orientation of the material on the conveyor line A111 and the conveyor line E211 to be consistent, so a workpiece correction mechanism is set up;

The workpiece correction mechanism includes a cutting mechanism and a direction adjustment mechanism 72; the first stop lever 711, the second stop lever 712 and the first displacement sensor 61 (along the material transportation direction) are provided at the front end of the direction adjustment mechanism 72; The second displacement sensor 62 (along the material transportation direction) is arranged at the rear end of the steering mechanism 72; the cutting mechanism includes: a first blocking rod 711, a second blocking rod 712, a first displacement sensor 61 and a second displacement sensor 62. Sensor 62; the first blocking rod 711 and the second blocking rod 712 move back and forth on the conveyor line to block/pass the material. In this embodiment, the first blocking rod 711 and the second blocking rod 712 are cylinders. , the first blocking rod 711 is close to the steering mechanism 72; its output end is extended and retracted to offset the material, fixing the position of the material at the front end of the steering mechanism 72, controlling the interval at which the material enters the steering mechanism 72, and realizing Blocking and releasing materials; the first displacement sensor 61 and the second displacement sensor 62 are signally connected to the first gear lever 711 and the second gear lever 712 for controlling the movement of the first gear lever 711 and the second gear lever 712 ;

Here is a detailed description of the control logic of the first displacement sensor 61 and the second displacement sensor 62 and the first gear lever 711 and the second gear lever 712: the setting interval between the first gear lever 711 and the second gear lever 712 is less than two units. The length of the workpiece of the one-way output shaft; and the first displacement sensor 61 is located close to the first blocking rod 711; when the one-way output shaft is continuously sent toward the direction adjustment mechanism 72, the first blocking rod 711 extends first, Block all the one-way output shafts at the front end of the steering mechanism 72. At this time, the first displacement sensor 61 detects the one-way output shaft located at the first position (that is, the first one blocked by the first blocking rod 711). , at this time, the second blocking rod 712 stretches out, resists the output shaft of the second one-way unit, and blocks all subsequent one-way output shafts; after the second blocking rod 712 resists, the first blocking rod 711 Retract, release the output shaft of the first one-way device, and let it enter the steering mechanism 72. After judging by the steering mechanism 72, if the direction is correct, it will be released directly. If the direction is incorrect, the direction will be changed and then released. After release, The first one-way output shaft will pass through the second displacement sensor 62. After the second displacement sensor 62 detects that the one-way output shaft passes, the first blocking rod 711 re-extends, the second blocking rod 712 retracts, and the remaining The position of the output shaft of the one-way device moves forward and is blocked by the first stop rod 711, and then the above steps are repeated; the execution original device used in this judgment logic is relatively simple. Two sets of cylinders and two displacement sensors can realize the control of all one-way The position control of the output shaft of the device allows the steering mechanism 72 to have enough time to determine the direction and perform the reversing action; wherein the first displacement sensor 61 and the second displacement sensor 62 and the first gear lever 711 and the second gear lever 712 are It is electrically connected to the PLC control box, and the PLC control box performs opening and closing control and signal processing.

The direction adjustment mechanism 72 includes a U-shaped frame 721; the U-shaped frame 721 is erected above the conveyor line A111, and a passage 7211 is opened inside the U-shaped frame 721 along the transportation direction of the conveyor line A111, so that the entire U-shaped frame 721 has a U-shaped structure; in the A first rotating motor 73 is provided inside the passage 7211; the output end of the first rotating motor 73 is provided with a direction-adjusting clamp 722 facing the surface of the conveyor line A111. The first rotating motor 73 can drive the direction-adjusting clamp 722 in the horizontal direction. Rotate 180°; the steering clamp 722 is provided with a reversing slot 7221 for materials to pass through, and the reversing slot 7221 is opened toward the surface of the conveyor line. In this embodiment, the output shaft of the one-way device is two different diameters. It is composed of concentric cylinders, so the reversing groove 7221 is a rectangular groove, and the groove width is slightly larger than the maximum diameter of the one-way device output shaft; the U-shaped frame 721 is also slidably provided with a plug that can approach/away from the reversing groove 7221 723; The plug 723 is driven by the cylinder and the strip bracket provided on the top of the U-shaped frame 721, and moves back and forth in the vertical direction; the plug 723 is provided with a third sensor 63; when the plug 723 faces the When the reversing groove 7221 moves to the maximum stroke, the plug 723 faces the reversing groove 7221 and blocks the material located in the reversing groove 7221 at the same time;

The working process of the steering mechanism 72 is introduced below: First, the structure of the wool material of the one-way output shaft must be clarified. As mentioned above, the one-way output shaft is composed of two cylinders with different diameters. The cylinder with the larger diameter is The end face is pre-opened with slotted holes, and the end face of the smaller diameter cylinder is flat; when the first stop rod 711 is retracted and the first one-way output shaft is released to enter the reversing groove 7221, the plug 723 is in advance at the maximum stroke at , one end of the reversing slot 7221 is blocked, so that the one-way output shaft cannot move after entering the reversing slot 7221 (the width of the plug 723 is greater than the width of the end face slot of the one-way output shaft), and the third sensor 63 is The judgment logic of the infrared sensor is reflection time. When it encounters a side with slots, the reflection time is longer. After judgment, the third sensor 63 will command the first rotating motor 73 to start and drive the steering clamp 722 to rotate in the horizontal direction. 180°, so that the flat end faces forward, and then the plug 723 is driven by the cylinder to rise, and the output shaft of the one-way device is released; if it encounters the flat end, after judging the reflection time, the plug 723 is driven by the cylinder to rise, directly to the one-way unit The output shaft of the diverter is released, and the existence of the steering mechanism 72 can reduce the requirements for front-end loading. There is no need to manually adjust the direction of the material, which reduces human labor and also reduces the structural requirements for the loading mechanism 8, making the loading mechanism 8 It only needs to meet the material loading requirements, and there is no need to add an adaptive direction adjustment structure internally. It also reduces the work steps and structural complexity of subsequent components to adjust the material direction.

The first transfer mechanism 4 includes a first slide rail 41, a first slide block 42, a first telescopic arm 43, a second rotating motor 44, and a dual-holding clamp set; the first slide rail 41 is erected through a stand 46 Above the conveyor line, perpendicular to the conveyor line from a bird's eye view; the first slider 42 is slidably disposed on the first slide rail 41, and the moving path of the first slider 42 covers the processing equipment and the first slider at the corresponding position. The second transfer mechanism 5 and the corresponding conveyor line; the first telescopic arm 43 is arranged on the first slider 42; the second rotating motor 44 is arranged on the free end of the first telescopic arm 43, and can be moved by the first telescopic arm 43. Driven by the arm 43, it is close to/away from the processing equipment, conveyor line and the second transfer mechanism 5; the dual-hold clamp set is set on the output end of the second rotating motor 44, and can be driven to rotate by the second rotating motor 44; dual-holding The clamp set includes two sets of first clamping jaws 45 arranged at intervals;

In this embodiment, the angle between the extension line of the output end of the second rotating motor 44 and the horizontal plane is 45°; one set of the first clamping jaws 45 is parallel to the horizontal plane, and the other set of the first clamping jaws 45 is parallel to the horizontal plane. 45 is perpendicular to the horizontal plane, that is to say, under normal conditions, there is always one first clamping jaw 45 parallel to the horizontal plane, and the other first clamping jaw 45 is perpendicular to the horizontal plane; when clamping the output shaft of the one-way device, if necessary To adjust the output shaft of the one-way device to vertical or horizontal, you only need to rotate the second rotating motor 44 180°, and the two first clamping jaws 45 will switch angles from perpendicular to the horizontal plane to horizontal to the horizontal plane (or vice versa). ), when the second transfer mechanism 5 delivers materials to the first clamping jaw 45 and when the first clamping jaw 45 places the processed one-way output shaft on the conveyor line, the one-way output shaft is in a vertical state, but due to During processing, the processing is performed on the horizontal end surface (or nearby position) of the output shaft of the one-way device. Therefore, it needs to be placed horizontally when it is placed in the lathe. Therefore, two sets of first clamping jaws 45 are provided at an angle to each other and a second control jaw 45 is provided. A second rotating motor 44 that switches the direction of the clamping claw 45 solves the problem of the direction of the output shaft of the one-way device;

Regarding the output end direction of the second rotating motor 44 and the structure of the dual-holding clamp set in the first transfer mechanism 4, the present invention also provides a second embodiment, as shown in Figure 6, in which the first transfer mechanism 4 The output end of the second rotating motor 44 is vertically downward, perpendicular to the horizontal plane, and the output ends of the two first clamping jaws 45 of the dual-hold clamp set are also vertically downward, and the two first clamping jaws 45 pass through the fixed plate It is fixed on the output end of the second rotating motor 44. This is because different types of processing equipment generally have two feeding modes. One is to feed the output shaft of the one-way device horizontally into the equipment, and the other is to feed the one-way device horizontally into the equipment. The output shaft of the machine is placed vertically inside the equipment, and two dual-holding clamp sets with different structures are set up to better adapt to different types of processing equipment;

Incidentally, on the conveyor line, a portal frame 99 for controlling the transport direction of the workpiece is provided at a downstream position where the first clamping jaw 45 feeds. The portal frame 99 is erected on the conveyor line and includes two legs and The blocking plate fixed on the free end of the foot; when the first clamping jaw 45 places the processed material on the corresponding conveyor line, it also needs to correct the direction of the material. The portal frame 99 can achieve this purpose; especially for rod-shaped materials. For materials, in the processing equipment, if the material is taken out vertically by the first clamping claw 45 and placed on the conveyor line, it will inevitably fall over, making it impossible to control the direction; when the first clamping claw 45 takes the material in a When the material is put into the conveyor line in a vertical state, the upper end of the material will contact the blocking plate, and the lower end will contact the surface of the conveying line. The first clamping claw 45 slowly releases, the upper end of the material is blocked by the blocking plate, and the lower end is driven by the conveying line. Since the transportation direction of the conveyor line is certain, the upper end of the material will be dumped on the conveyor line at a predetermined angle to achieve orientation correction and facilitate processing in subsequent sections;

In addition, in the actual production process, after the two drilling and grooving equipment 24 are processed, since it is the final work section, there is no need to put the materials into the conveyor line, but directly into the drilling and grooving equipment 24 It can be collected in the finished product collection device 10 next to it.

The second transfer mechanism 5 includes: a second slider 51, a second lifting cylinder 52, a third rotating motor 53 and a second clamping claw 54; the second slider 51 is slidably disposed on the side of the conveyor line, and the sliding direction is consistent with the conveyor line. The transportation direction is parallel, and the sliding path of the slide block covers the material cutting mechanism, so that the movement trajectory of the second clamping claw 54 can cross the material cutting mechanism and transport the material to the downstream of the conveying line; the second lifting cylinder 52 is provided at on the second slider 51; the third rotating motor 53 is fixed on the second lifting cylinder 52, and can be driven by the second lifting cylinder 52 to reciprocate in the vertical direction; the second clamping claw 54 is fixed on on the output end of the third rotating motor 53, and driven by the third rotating motor 53 to rotate in the vertical direction;

The following describes the cooperative working process of the first transfer mechanism 4 and the second transfer mechanism 5: the second clamping jaw 54 maintains a horizontal state in standby, and when the material is transported to the interception mechanism via the conveyor line, it is intercepted by the interception mechanism; The second clamping jaw 54 is first driven by the third rotating motor 53 to rotate in the vertical direction toward the material, and then the second lifting cylinder 52 drives the second clamping jaw 54 to approach the material to clamp the first stopped material; Then the second lifting cylinder 52 drives the second clamping jaw 54 to rise, keeping the clamped material away from other materials and the surface of the conveyor line, leaving room for rotation; the third rotating motor 53 reverses, causing the second clamping jaw 54 to return to a horizontal state. , at this time, the clamped material is in mid-air and is easier to be clamped by the first transfer mechanism 4; the second clamping jaw 54 remains horizontal and waits for the first clamping jaw 45; when the first clamping jaw 45 pulls the material from the processing equipment After the processed one-way output shaft is transferred to another conveyor line, it will move over to clamp the material in the second clamping jaw 54, and then send it to the processing equipment 2 for processing; during the processing of the processing equipment 2, the second clamping jaw 54 is rotated again to face the remaining material, and the second material is clamped. The second lifting cylinder 52 drives the second clamping jaw 54 to rise, and the second slider 51 moves, so that the second clamping jaw 54 is clamped. The material passes through the stopping mechanism, and then the second lifting cylinder 52 drives the second clamping jaw 54 to descend, and the second clamping jaw 54 is released to transport the material to the downstream; generally speaking, the model of the processing equipment used in a work section The same, the processing time is also the same; determine the number of processing equipment, and set the same number of stop mechanisms, first transfer mechanism 4 and second transfer mechanism 5 again; feed and replenish materials to the downstream according to the processing time of the corresponding processing equipment. , will greatly reduce the stagnation time of materials on the conveyor line and shorten the processing cycle of materials. Especially for processing production lines with multiple equipment combinations, this coordinated feeding and transportation method ensures that the processing equipment can operate at full load, avoiding The empty machine situation is eliminated and the processing efficiency is improved; among them, the first transfer mechanism 4 and the second transfer mechanism 5 are electrically connected to the PLC control box, and the PLC control box performs opening and closing control and signal processing;

The function of the second transfer mechanism 5 is: after the first transfer mechanism 4 puts the material clamped by the second transfer mechanism 5 into the processing equipment, the second transfer mechanism 5 clamps the second material stopped by the cutting mechanism, After crossing the cutting mechanism, the material is transported from the conveyor line to the next cutting mechanism, waiting for processing; the advantage of this is to effectively realize the coordinated replenishment of multiple equipment. When there are several processing equipment, the conveyor line moves towards the processing equipment. There will be difficulties in loading logic; because all the materials to be processed are put on a conveyor line to wait for processing, and the conveyor line is full of materials, there will be a situation where the clamping equipment is inaccurate, that is, the materials cannot be accurately grasped or Improper grasping position will cause the material to slip or shift, affecting the position of the material into the processing equipment; the existence of the cutting mechanism allows the first transfer mechanism 4 to have a pre-positioning function, and the second transfer mechanism 5 will pre-clamp it , allowing the material to maintain a predetermined station, and then transfer it to the processing equipment by the first transfer mechanism 4, which not only shortens the material loading time, but also improves the clamping accuracy of the first transfer mechanism 4;

A fourth displacement sensor 64 is provided on the conveyor line and downstream of the second transfer mechanism 5; the fourth displacement sensor 64 is signal-connected to the second transfer mechanism 5 and is used to control the second transfer mechanism 5 to transfer the material from The material mechanism is transported to the downstream. The control logic of the fourth displacement sensor 64 is introduced here. The distance between the fourth displacement sensor 64 and the upstream second transfer mechanism 5 is set to the sum of the lengths of a certain number of one-way device output shafts. When the unit When the output shaft of the one-way device passes the fourth displacement sensor 64, it means that there is still a certain space at the front end of the second transfer mechanism 5 downstream, and the second transfer mechanism 5 upstream can continue to feed materials. When the output shaft of the one-way device accumulates to a certain number, It will stop below the fourth displacement sensor 64, and the fourth displacement sensor 64 cannot detect the movement. At this time, the fourth displacement sensor 64 sends a signal to let the upstream second transfer mechanism 5 stop feeding; therefore, as long as there is a single The output shaft of the one-way unit is transferred by the second transfer mechanism 5, and the remaining output shafts of the one-way unit will make up the movement. After the fourth displacement sensor 64 detects the motion signal, it can immediately send out a signal, and the upstream second transfer mechanism 5 will Replenishing materials can effectively shorten the stagnation time of materials on the conveyor line, ensuring that there are materials in front of the 5th station of each second transfer mechanism, shortening the processing cycle of materials, and improving processing efficiency. Among them, the fourth displacement sensor 64 and the second transfer mechanism Mechanism 5 is electrically connected to the PLC control box of the corresponding section, and the PLC control box performs opening and closing control and signal processing;

The cutting mechanism is a block 3 with a rectangular structure; it is arranged radially on the conveyor line, but does not contact the surface of the conveyor line (the purpose is not to cause friction with the surface of the conveyor belt when the conveyor belt is running); The stopper 3 is provided with a positioning slot 31; the notch of the positioning slot 31 is opposite to the transportation direction of the conveyor line, and is used to limit the stopped one-way output shaft when the one-way output shaft is stopped. position to prevent it from turning horizontally.

In this embodiment, the front end of the conveyor belt A is provided with a loading mechanism 8. The loading mechanism 8 is a pallet-type loading machine, which can dump the one-way output shaft on the pallet onto the conveying line A111. The fifth displacement sensor 65 is provided on the conveyor line, that is, the conveyor belt C; the fifth displacement sensor 65 is provided between the loading mechanism 8 and the workpiece correction mechanism, and is connected with the signal of the loading mechanism 8, and its judgment logic is the same as that of the fifth displacement sensor 65. The four displacement sensors 64 are similar, except that the fifth displacement sensor 65 is provided with delay logic. Since the output shaft of the one-way device will have a certain adjustment time in the workpiece correction mechanism, and the quantity of materials loaded by the pallet loader is random, therefore The loading mechanism 8 cannot continuously feed materials, otherwise it will cause material accumulation between the loading mechanism 8 and the workpiece correction mechanism. Therefore, when the fifth displacement sensor 65 senses the displacement, a delay logic is set to control the pallet loader. After a certain period of time, the material is loaded, and a processing time of an indefinite number of materials is reserved, and then the material is replenished by the feeding mechanism 8. The fifth displacement sensor 65 and the feeding mechanism 8 are electrically connected to the PLC control box of the corresponding section. connection, the PLC control box performs opening and closing control and signal processing.
